Solar Panels

Use of solar energy to power homes helps in a number of ways. First of all, it reduces your dependency on the grid. Second, it helps reduce pollution levels to a certain level. Third, it helps save a lot of money by bringing down your electric bill. 

It also provides you with an opportunity to earn money by selling excess energy that you produce back to the grid. Want to know more about solar panels and know how to install them? Then keep reading till the end.

What is a Solar Panel?

A solar panel is a component of a photovoltaic system that converts light from the sun into electricity. These panels are made up of crystalline silicon-type photovoltaic cells. A large number of cells spread over a large area work in unison to provide an adequate amount of power that is useful. They come in a variety of rectangular shapes. These panels are arranged in parallel or series alignment for the purpose of observing sunlight and generating direct current (DC). You can use solar panels to supplement electricity requirements for both urban as well as remote locations for both residential and commercial use. Depending on the type of panel, light energy will convert into electricity. There are a total of seven main components that are combined together for making up a single PV module.

What is the Process of Making Solar Panels?

Now that you know what a solar panel is, the next question in your mind must be the process of preparing them.To answer this question here are the steps that technicians usually follow to prepare solar panels:

Step 1

First of all the cells are cut using laser cutting machines. The size of a cell is determined by wattage of panels. In case of a full cell-sized module, cell-cutting process is completely skipped.

Step 2

Next comes stringing process, which includes assembling or soldering the cells together. The part of solar panel that faces the sun which is usually black or blue is negative while the other part or white side is positive.

Step 3

After the cells are stringed together, they are transferred to tempered glass. These have ethylene vinyl acetate encapsulation layers over them.

Step 4

Next these cells will be examined by technicians to find if there are any faults or not.

Step 5

After this the cells are taped into matrix alignment.

Step 6

Then connections are smouldered together and extra material is cut off.

Step 7

Next step involves insulating the connections using ethylene vinyl acetate encapsulation and a back sheet. This is done for the purpose of protecting solar panels from dust and moisture.

Step 8

The module is checked once more for any dust particles or colour mismatch etc.

Step 9

Next comes El testing or electroluminescence test. In this, modulesare scanned in an El machine. This is done to spot any dead or low-power cells, cracks, short circuits etc. In case technicians find any fault, then the module is sent back for fixing the issue.

Step 10

After this the module is laminated. A temperature of 140 degrees centigrade is used for this process which takes around 20 minutes.

Step 11

Next the back sheet is trimmed so as to perfectly shape these modules.

Step 12

After this frames of different sizes are cut out for the purpose of bordering panels.

Step 13

Next comes frame punching, in which holes are punched for the purpose of mounting and grounding of panels.

Step 14

Then sealant is filled in these panels so as to protect them from dust, air and moisture. The sealant also makes sure that the frame gets firmly attached to the frame. Once it is done the panel is sent to framing machine for the purpose of attaching panel permanently to frame.

Step 15

A junction box is attached to the panel with a sealant so that it gets firmly attached to the structure. The connections are smouldered and left for 10 to 12 hours to perfectly dry and attach properly.

Step 16

The technicians then clean the module by wiping the outer side in order to remove traces of dust, excess sealant or foreign particles.

Step 17

Lastly the module is connected so as to check whether output current, voltage etc. are perfect. After the test, a report is made stating output data of each module. A label is pasted at the back of module for benefit of users. After this, it is sent to QC lab for testing insulation resistance. 3000 V Direct Current is passed through the module for a minute. If the module is able to endure it then it passes or else it fails. After this, the module is sent for Mechanical Load Test. After completion of Final Quality Assurance, solar panel manufacturing process comes to an end. Post this packaging of the modules starts, where they are packed in large boxes for transportation and storage. Das Energie Private Limited offer solar panels made by some of the top solar manufacturers in the country. Therefore you do not need to worry about the quality.

How Do Solar Panels Work?

Now that you are aware of what a solar panel is and how it is made, next question that might normally arise is how these solar panels work. To find an answer to this question please go through steps mentioned below:

Step 1

When sun rises, the photovoltaic cells that are arranged together in groups in order to form the solar panel absorb the photons from it.

Step 2

As soon as the photons are absorbed, the electrons from the silicon atom are knocked free by the panel's metal conductors.

Step 3

After the solar panels absorb sun rays it is converted into electricity by creation of electric fields between positive charge on one side and negative charge on the other. You can arrange as many solar panels as you want to provided you have the space for it. More the number of panels arranged together, more energy that can be generated. The DC that is generated can be maximised with the help of an MPPT charge controller unit. An inverter is required for converting direct current into alternating current.

Features of Solar Panel

Now that you are aware of what a solar panel is and how does it work it is important to take a look at the features as well. Here are the basic features of solar panels that differentiate one type from another

Raw Material

Solar panels are made of solar cells and each type of solar panel is made of different solar cells. In case of monocrystalline, pure silicon is used as raw material while in case of thin film solar panels, it might be Cadmium Telluride or Copper Indium gallium Selenide.

Frame Thickness

This is also a characteristic factor that impacts the quality of solar panels. The solar panel made of an aluminium structure may have around 30-millimetre to 45-millimetre frame thickness.

Module Size

There are different sizes of solar panels available in the market. Smaller solar panels require less space wherever you install them. A smaller size solar panel fits in lesser space therefore it costs more as well.

Unbreakable Glass

Foldable solar panels are made of foldable glasses that have lesser chances of breaking. This type of solar panel might be more expensive than the ones which do not have foldable glass.


Nominal Operating Cell Temperature is another important feature that distinguishes different quality solar panels. This factor states how the panel is going to perform in realistic conditions once it is installed.

What are the Different Types of Solar Panels Available?

You can categorise solar panels into 4 main types. These are as follows:

Monocrystalline Panel

Also known as single-crystal panels, monocrystalline solar panels are made of single-crystal silicon solar cells. Pure silicon is formed into bars and sliced into several wafers for the purpose of constructing this type of panel. This is the oldest and most developed out of the four types available these days. Due to its efficiency and power capacity, it is the most commonly used solar panel. They are easy to recognise with their signature black colour and rounded corners. Monocrystalline solar panels have a technology which is known as Half Cut cells. In this, the square-shaped cells are cut in half for creating twice the number of cells. The upper half of the panel has all the cells connected into one series. While the bottom half is connected to another series. This technology helps in power generation when the other half is in shadow. For example, if the bottom half is in shadow the upper half can still produce power and vice versa. Therefore this technique solves the problem of power generation in case of partial power shadow issue.

Features of Monocrystalline Panels

Let us take a look at some of the features of monocrystalline solar panels:

Monocrystalline panels have high conversion efficiency. This means it produces more kW/hour of electricity. This is because these panels are produced of a single silicon crystal which permits more space for the electrons to move.
As the manufacturing process of single-crystal silicon cells is complicated therefore monocrystalline panels are expensive in comparison to other types of panels.
The heat resistance capacity is higher in case of monocrystalline panels in comparison to other types of panels. This means that these panels can produce electricity at higher efficiency even in high temperatures without being too affected by the heat.

Das Energie Private Limited offers monocrystalline solar panels manufactured by the top solar brands in the country. They are available in varieties of capacities as well. If you wish to buy them, contact us today.

Polycrystalline Panel

This type of solar panel is made of solar cells that are produced of fragments of silicon crystals. Therefore these solar panels are also known as multi-crystalline modules. These modules are made of the silicon waste left behind during production of pure silicon crystals. The leftovers are then melted together into a mould. These moulds are then sliced into thin wafers and are then assembled together for the purpose of creating polycrystalline panels.

Features of Polycrystalline Panels

If you compare with monocrystalline panels, then the efficiency is much lower in case of polycrystalline panels. As these panels are made of multiple silicon crystals therefore there is lesser space for the electrons to move.
However, in terms of cost, polycrystalline panels are much more affordable than monocrystalline panels. This is because the manufacturing process is much more simpler and lesser silicon is wasted during production process.
Poly modules come with much lower wattage and therefore have a lower power output in comparison to monocrystalline panels.
You can identify the polycrystalline panels by their square shape cells with straight edges and shiny blue tint.

We at Das Energie Private Limited provide all capacities of polycrystalline solar panels that are manufactured by top-notch solar manufacturers. Call us to get your quote today.

Passivated Emitter and Rear Cell (PERC) Solar Panel

Mono PERC or Passivated Emitter and Rear Cell solar panels use relatively advanced technology. Also known as rear cells, this is an upgraded version of Monocrystalline modules. Its name rear cell is due to the fact that a layer is also present at the back of the solar cells. The traditional solar panels are unable to absorb all the sunlight that it receives and some light passes through them. In order to counter this problem, an additional layer is present in the PERC panels. The layer present on the back of the solar cells absorbs whatever unabsorbed sunlight passes through the back of the cells. This technology makes this type of panel much more efficient. PERC technology along with monocrystalline cells helps this type of solar panel receive highest power rating among all the types of solar panels available commercially.

Features of Passivated Emitter and Rear Cell (PERC) Solar Panel

Both in terms of efficiency and power output PERC solar panels are the best available in the market.
This type of solar panel absorbs light that is reflected by the ground.
If you are to compare the costs, then PERC solar panels are the costliest in the market.
Thin Film Solar Panel

Thin film solar modules are lightweight and slimmer in comparison to monocrystalline and polycrystalline modules. Unlike mono or polycrystalline panels, these do not rely on silicon and are produced using other types of photovoltaic substances. There are three different photovoltaic substances using which thin film solar modules are manufactured. These are:

Amorphous Silicon (a-Si)
Cadmium Telluride (CdTe)
Copper Indium Gallium Selenide (CIGS)

In order to produce thin film solar modules the manufacturer places these materials between two transparent conductive layers. These conductive layers are mostly made of glass or plastic which makes it lighter as well as easy to install.

Let us now take a detailed look at the three different categories of thin film solar panels

Cadmium Telluride (CdTe)

This type of solar panel has the lowest carbon footprint among all the other types available in the market. However, Cadmium is a highly toxic element, if inhaled or ingested and it might become an environmental concern as it is not recyclable easily. If we consider the production of its solar cells, we will see it is relatively low cost and has the shortest payback time. Other than that during production, it requires the least amount of water. Due to its shortest energy payback time, it has the least carbon footprint.

Amorphous Silicon (a-Si)

This type of solar panel uses a triple-layered technology, which is considered best among the varieties of thin film solar modules. These panels are generally shapeless in nature as the silicon in this case is unstructured on the molecular level. It has lower efficiency in comparison to crystalline silicon; however, the price is also comparatively lower. This technology is most commonly used in pocket calculators.

Copper Indium Gallium Selenide (CIGS)

This type of solar panel is manufactured using a thin layer of copper, indium, gallium, and selenium on a glass or plastic sheet. CIGS modules have the highest efficiency in comparison to all other thin film solar panel categories due to their high absorption abilities.

Features of Thin Film Solar Panels:

  1. Thin film solar panels are comparatively lightweight as well as flexible in comparison to traditional silicon solar panels. Other than that due to its size and high movability, these panels are comparatively easy to install.
  2. These panels might be either blue or black depending on the material using which it is produced.
  3. Thin film solar panels have much less efficiency in comparison to silicon crystalline panels. However, these are cheaper than silicon crystalline panels and also have a lesser carbon footprint.
  4. Thin film solar panels are more suitable for places that have wide open spaces or large rooftop areas.
  5. These solar panels have a smaller shelf life. Therefore it is not suitable for residential or commercial purposes and can be better employed for utility-scale projects.

We at Das Energie Private Limited sell all types of thin film solar panels. These are from the best brands and are of the best quality. We are just a call away. Contact us and we will offer you the best deals possible.

Depending on the technology, all these types of solar panels have been classified into 1st generation, 2nd generation and 3rd generation. 1st generation solar panel category includes monocrystalline and polycrystalline as these are the most conventional ones.

While in case of 2nd generation category, thin film solar panels like amorphous silicon are present. This is because these panels are mostly used for photovoltaic power stations, smaller solar systems and in buildings.

3rd generation solar panels also include some varieties of thin film technologies. They are included in the 3rd generation because they are in the research and development phase.

Factors to Consider While Choosing the Best Solar Panel

All solar panels look the same. However, there are certain factors that you need to consider before understanding as to which solar panel is best and suits your requirement the most. Therefore here are certain features that might help you choose the solar panel that is best for you


Before purchasing a solar panel it is important to consider its durability. The solar module should be made of high-quality materials as well as designed to withstand harsh weather conditions for at least a quarter of a century. You can see that certain solar panels have the capacity to outlive the roof. If the solar panel comes with the assurance that it is resistant to any type of extreme weather then only will it be an ideal one. Not all that a brand promises happens in real life. Therefore you need to purchase your solar panel from a reputed brand.

Low Maintenance

While deciding which solar panel to purchase it is important to choose a solar panel that does not require too much of maintenance. In general maintenance of solar panels does not consume too much time. Other than removing the dust and leaves that might accumulate on top of the panels there is not much that you need to do. However, you need to purchase the panels from a well-known brand so that you can make the most of the 25-year warranty.

Conversion Efficiency

How much power your solar panels will be able to generate depends on the efficiency of the solar panel to transform light into electricity. In case two solar panels have the same price. However, one of them has more efficiency than the other then the one with higher efficiency offers better value for money. Therefore you need to choose the one with better efficiency. Apart from the price of a solar panel, you also need to consider the materials used to manufacture it.

Cost Effective

Solar panels do not require any fuel or other inputs for generating electricity. They also help in saving a lot of money by reducing our electric bills to a considerable extent or totally removing it. Therefore it is best to choose your solar panel from a manufacturer that offers the best quality solar panels.


Smaller solar panels occupy lesser space on your rooftop or wherever you mount them. Thin film solar panels are lightweight as well as easy to install in comparison to all other types of solar panels. This makes them ideal for remote locations. You, therefore, need to choose solar panels according to the space that you can afford.

Temperature Coefficient

The temperature co-efficiency rating is crucial for determining the impact of heat on operation of solar panels after installation. The lower the percentage by degree the better it is. Though cost of better temperature co-efficient panels might be higher. However if you consider our country's rising temperatures, then investing this additional cost might be worth it. Das Energie Private Limited offer solar panels produced by some of the top-notch brands in India. Therefore there are a wide range of options available for you. Choose the one that suits your requirement the most and we will make sure that you get it at a reasonable rate as well.

Benefits of Solar Panels

Using solar energy is a great way to reduce the pollution levels of the world as you do not have to burn anything to create energy. As there is no need to burn anything therefore there is no release of harmful by-products in the atmosphere. Not just that being a renewable source of energy, there are no chances of a decline in supply, in case of sunlight. By using solar energy you become independent in terms of creating your own energy as well as increasing electricity bills. Solar panels are a great way to meet household electricity requirements. Other than this there are quite a few other potential benefits of solar panel installation. These are:

Cheaper Electricity Bill

The more electrical appliances you use the higher will be your electricity bill. By using solar panels you can reduce your electric bills considerably. In case you use an off-grid solar power system your electricity bill will be nil. Energy generated by solar panels is completely free after the price breaks even after a few years. Energy generated by solar panels is completely free after the price breaks even after a few years. You can either store or export back the surplus energy that the panels generate back to the grid.

Year-round Efficiency

Solar panels can usually generate energy all year round. They work optimally during summer months and produce considerable amounts even on cloudy days and winter months.


Houses that have solar panel installation are ready for any type of natural disaster as well as grid failures. In case there is a power cut due to some issue with the grid, you can use the stored energy from the batteries. And as soon as the sun rises you can recharge the battery once again.

Earn Back Money

In case you opt for a solar panel without a battery, you can sell the excess electricity that the solar panels produce back to the grid. This acts as a great way to earn quite a good return on investment.

Independent From Grid

Solar panels with batteries are an effective solution for remote areas where extending power lines from the electric power grid would be much more expensive. In comparison to grid connections solar panels are much more affordable. By opting for a solar system, you get the added advantage of storing excess energy that the solar panels generate into solar batteries. This will certainly help on rainy days and throughout the night.

Low Maintenance Needed

Solar panels last up to 25 to 30 years that too with just a minimal amount of maintenance throughout their lifespan. While a solar inverter has a lifespan of 10 to 15 years. Other than light cleaning and inspection by technicians once in a while, there is not much hassle in maintaining solar systems. Roof-mounted are mostly self-cleaning as rainfall helps in removing the accumulated dust. While installing you need to make sure that no trees cast shadows over the panel as this will reduce their efficiency.

Reduces Carbon Footprint

Solar is a renewable source of energy therefore it helps to reduce carbon footprints consequentially. As you are aware using fossil fuels, oil and coal for production of electricity releases carbon dioxide and other pollutants. By installing domestic solar panels you can reduce around one tonne of carbon dioxide production. And this will be around 25 tonnes for the entire lifetime of a solar panel. Therefore you will be able to make a huge difference by going solar.

Increased Value of Home

When you install solar panels it increases the value of your home. However, how much value the system has helped increase depends on the size of the system. If you wish to make the most of these benefits contact Das Energie Private Limited today to get thee best deals on top quality products.

Drawbacks of Solar Panels

Despite having a large number of benefits, there are also some drawbacks to using solar panels. These are

High Initial Cost

Investing in solar panels might be quite expensive. Though after 3 to 4 years the money spent on them breaks even and you start earning by selling excess energy to the grid. However, meeting the high initial costs might be tough for most of the people.

Solar Panel Placement

Your house needs to meet certain requirements when it comes to installation and efficiency of solar panels. In case your house is surrounded by large buildings on all sides the efficiency of the solar panels might be compromised. You also need to make sure that there are no tall trees surrounding the panels for the best efficiency.


Though solar panels do not require much maintenance, however, there are certain maintenance items that the owner needs to consider. This includes annual or semi-annual cleaning so as to preserve efficiency. In case the roof underneath the panels requires replacement or repair, it might significantly add to the prices of maintaining the panels.

More Efficiency During Daytime

As solar panels are dependent on sunlight, they are unable to produce energy during the night. Not only that as the solar panels generate energy only when there is direct sunlight, they are less effective during dark winter days as well.


Many homeowners do not prefer installing solar panels as they do not look good and do not add to the beauty of their homes. However, if they install off-roof systems on a set of racks or mount them away from the home then appearance might not be an issue. But if you are planning to do so then you have to pay extra for the hardware, cables as well as the design of the panels.

What are the Factors that Affect the Efficiency of Solar Panels

Efficiency of solar panels does not solely depend on the sun. There are many other factors that impact the efficiency of the solar panel. These are


The efficiency of solar panels varies with temperature. The lesser the temperature the better the efficiency. With the rise in temperature, the semiconductor properties shift which results in a slight increase in current but a large decrease in voltage. Extreme high temperatures may even damage the panels resulting in a shorter lifespan. As the sunlight shining on the panels transforms into heat proper thermal management improves the efficiency as well as lifespan of the panels.


Solar panels have an average lifespan of 20 to 25 years. During the entire lifespan of the panel, there are various internal and external factors that affect their efficiency. As the years pass by the solar panels lose some percentage of efficiency. However, according to some experts, the performance of solar panels improves as they age. This however depends on the quality and type of solar panels.


Materials accumulate on the surface of the PV panel that can block sunlight from reaching the solar cells. Dust, leaves, and bird droppings accumulation over some time might reduce power generation consequentially.


Efficiency of solar panels depends on shading, as it influences the overall amount of energy that the solar panels generate. In case there is an obstruction due to trees, buildings and other objects it would affect the current travelling through the entire panel reducing the overall efficiency. This might even result in damage if you are unable to remove the shade.

How to Install Solar Panels?

Solar panel installation requires professional help. This is because any mistake while installation might reduce the efficiency as a result of which the panel might produce lesser power than it is capable of. However, it is better if you have a rough idea about the entire installation process so that you can confirm what the technician is doing is right. Here are the steps that the technicians generally follow during installation of solar panels:

Step 1: Setting Up Scaffolding

The first step is to erect a temporary structure made of wooden planks so as to ensure safety of technicians during installation of panels on the roof.

Step 2: Installing Solar Panel Mount

Next comes setting up the solar panel mounting system. The mounting system supports the base of the solar panel. Firstly the technicians install the solar panel mounting brackets. They can use roof ground mounts or flush mounts on the basis of the application. Orientation of the PV panel in which they will be mounted must be carefully considered. If you want to install a solar panel in the northern hemisphere then the panel must face south to receive maximum amount of sunlight. While in case of southern hemisphere, it will be vice versa. The mounting structure needs to be titled between 18 to 36 degrees so as to have maximum sunlight exposure. You can also use a solar tracker for increasing conversion efficiency.

Step 3: Installing Solar Panel in Place

After setting up the mounting structure, the technicians will secure the solar panel to the mounting structure. They will make sure that the bolts and nuts are tight enough so that the entire construction is secured adequately for it to be durable and long-lasting.

Step 4: Installing Electrical Wiring

Next comes installation of electrical wiring. While cabling, MC4 connectors can be used to connect solar panels as these are universal connectors and can be used with different types of solar panels. One thing that you must keep in your mind during wiring installation is to shut off the household's electric supply. There are some modern solar panels available in the market that comes with wire leads that include MC4 connectors on the end. While the others have built-in junction boxes at the rear side of the panel with wires jotting out. Following sequences of electric connection are necessary between the solar panels depending on the type of connection

Series Connection: In case of a series connection, the technician will connect the positive wire of one solar PV panel to another panel's negative wire. The voltage match of the battery bank will improve if this type of wiring is this case.
Parallel Connection: While in case of parallel connection, the technician will link positive wire of one solar module with the negative wire of another module. By doing so the panel's wiring voltage remains same.
Step 5: Connecting Solar Panels to Solar Inverter

After wiring is complete, the technician will connect solar panels to solar inverter. They will necessarily install inverter near the solar panels.However, you can install it either indoors or outdoors according to your convenience. If you install the solar inverter in a cooler place then its efficiency will be better. Even if you install it outdoors, you need to keep it out of afternoon sun. During this process, the technician will link positive wire of the solar panel with the inverter's positive terminal.While the negative wire of the solar module needs to be connected to the negative terminal of the inverter. Other than this some more connections are required for generating power. These are battery wire connection and output wire connection with the inverter. The panels, solar battery and grid input need to be connected to the inverter for producing electricity.

Step 6: Connecting Solar Inverter to Solar Battery

In case of an off-grid solar system solar battery is a must for creating a power backup. As this type of solar power system does not have any connection with the grid. Therefore you need a battery for storing excess power for using it when there is no sunlight. The batteries are a saviour in case of a cloudy day as well. The positive terminal of the battery requires a connection with the positive terminal of the inverter. In a similar manner, the negative terminal of the battery requires a connection with the negative terminal of the inverter.

Step 7: Connecting Solar Inverter with Power grid

Next is connecting the solar inverter with the grid. For this, a standard plug is also acceptable. This plug needs to be plugged into the main power switching board. The output wire that is connected, is the one through which the electricity board supplies electricity to your home. This step is applicable only in case of on-grid solar systems that have a connection with the utility grid.

Step 8: Switching on the Solar Inverter

After establishing the connection between solar panel, inverter and battery or grid, next is to turn on the inverter by switching on the main switch. This will help in testing whether the newly installed solar panels are working properly or not. Generally, inverters have a digital display that shows total solar units generated during the day. This will help in planning out your daily chores like using your washing machines as well as other appliances on the basis of how much electricity the panels generate at different times. Earthing is also a crucial part of installing solar panels. It is preferrable in soft soil rather than a concrete area. Earthing must be done as close to the solar installation as possible so as to reduce the length of cables required. We at Das Energie Private Limited have an experienced team of technicians who will offer a hassle-free installation process. You simply have to contact us and relax as they will do their job with absolute perfection without you having to worry. Therefore contact us today to get the best services at a nominal cost.

Maintenance of Solar Panels

Solar panels usually require very little maintenance for functioning properly. Therefore after covering the basic installation cost, there are no major costs that you have to bear. However, one thing that they need is periodic inspectionsa few times each year. This is necessary so as to make sure there is no dirt, leaves or other debris obstructing the sun’s rays. As some solar panel manufacturers have certain terms and conditions regarding self-cleaning of solar panels with a warranty. Therefore you need to consult the installer before cleaning the panel yourself. Here are some tips as to how you can clean the solar panels with the least effort:

You can use a leaf blower to remove any leaves that might accumulate over some time.
A normal garden hose might be fine for a quick spray to wash the face of the panel. However, avoid spraying cold water on the solar panels when they are hot as this might damage them.
You can also purchase a solar panel cleaning kit that is available in the market. In this kit, you will get biodegradable soap, a wiper, a small brush, and a brush with a long handle. The instructions as to how to use them are also available in the kit. You need to mix the soap in a bucket of water and dip the brush in the bucket and gently wipe the solar panels.
Other than this you can also use plain water and a soft brush to remove any dirt built on the panel.
In case spraying water is not enough you can use a sponge with soap water for scrubbing the panels.
During winter you need to clean the panels after heavy snowfall. In case you want to clear snow make sure to use lukewarm water. Other than you can also use a squeegee with a long handle for this purpose.
The cloth that you can use to clean the panels should be non-abrasive to prevent scratches as well as a microfiber cloth that is soft on the surface.
If your solar panels are ground-mounted it is comparatively easier to access in comparison to roof-mounted panels. You can use a soft-bristled broom to clean it.
While if the panels are roof-mounted you need to use a safety harness or ropes so as to prevent falling. You can also use a ladder for this purpose.
The best option would be to use a telescopic pole and a microfiber cloth attached to it for safely cleaning the solar modules from the ground.
Make sure to not use any harsh material for cleaning solar panels. This might cause damage to the solar panel. And repairing solar panels might be quite an expensive affair.
Clean the solar panels when they are wet so that any residue that is stuck on them can be wiped easily.

Maintaining the solar panels is crucial for ensuring its longevity and efficiency. You also need to make sure of small things like checking whether the solar inverter is flashing green light. In case it is not so then you need to immediately repair it. You can use a monitoring app to keep track of the amount of energy your solar panel produces. In case you notice any dip, it might be time for cleaning the panels. Only cleaning the solar panels does not do the trick. If the solar panels are too old or damaged or not working you need to consider the option of replacing them.

We at Das Energie Private Limited offer a Solar AMC to all our customers. Therefore if you want to lead a hassle-free life, go ahead with it and forget about the worries of regularly maintaining your solar panels. Our technicians will visit you annually to take good care of your panels. This will ensure that the panels do not lose their efficiency and operate for a long time.

Factors Affecting Cost of Solar Panels

There are various factors that you need to take into consideration while calculating price of 1 solar panel. These include manufacturing technology, model type, type of material etc. Apart from these, there are a few more additional factors that influence prices of solar panels. These are


The brand of the solar panel you are planning to purchase affects the price. If you are planning to purchase solar panels from a reputed brand you have to spend more in comparison to if you purchase them from any local brand.

Type of Roof

The price of solar panels might alter depending on the type of material of your roofing. Many manufacturers might charge different rates for different roofing materials.

Age of the Roof

In case your roof is old and requires repair it is best to make the necessary changes as the solar consultant asks. This might increase the installation costs to some extent however it will ensure longevity of the solar system.

Chargeable Tax

Taxes are chargeable for installation of solar panels in certain areas. This might increase the price of solar panels to some extent.

Cost of License

Different regions have different rates for installation of solar panels. Therefore if you are planning to install solar panels in one area it might be costlier than if you install it in another region.

Market Value

In case demand for any specific model of solar panel is surging then the price of that model might also rise in comparison to other models.

If you install a solar system in your house the most important component are the solar panels. You need to choose solar panels that best suit your requirements. There are various subsidies available by the state governments in case you are shifting to solar. If you apply for the subsidy, you will receive it after 30 days of installation of the solar system.

Frequently Asked Questions

In order to boost India’s effort towards creating solar power capacity at a better rate, price of Chinese solar panels has dropped quite a lot. This is due to a fall in polysilicon prices as there is an oversupply situation in the European markets. Therefore we can now say it with a guarantee that the prices will drop further if this situation persists.

As the name suggests bifacial solar panels are panels that generate electricity from both sides. Both the front and back sides of bifacial panels generate power as solar cells are present on both sides. You can find various varieties of bifacial solar panels in the market like monocrystalline and polycrystalline panels.

In order to calculate the number of solar panels required you need to multiply your hourly energy consumption by the number of peak sunlight hours in the region you want to install solar panels. After this, you can divide the result by each panel’s wattage.

Charging a battery directly from a solar panel is quite easy. However, the first thing you will require for this is a charge controller. The charge controller regulates the voltage being transferred from the solar panel to the battery.

Solar panels on an average cost something around ₹36,000 to ₹40,000 depending on the type, brand and model that you choose. In case you choose monocrystalline solar panels it will cost you more than bifacial and polycrystalline solar panels.
